CNC router table

I intend to upgrade my CNC machine. The table will be constructed of Bosh - Rexroth Al profiles. This model is a first attempt to design a table that can be set to different heights with a mechanism similar as a car jack. The scissor mechanism will be used for a rough settings while the leveling will be made with fine adjusting blocks (seen in one of the detailed images). The whole assembly will be mounted on the existing machine https://grabcad.com/library/cnc-mill-beta-version-1 only the old table https://grabcad.com/library/cheap-cnc-table-1 will be removed
